Unable to boot Kernel-2.6.5-mm6 on P4 with HT Support
 

Hello friends!
After long and exhaustive tries, I managed to shift to Kernel-2.6.5 on Red Hat Linux 9 (Shrike).
The purpose to make this shift was because of my SATA HDD and P4 HT Support.
The Kernel that I downloaded from Kernel.org solved the SATA problem and though it also detected the HT capability of my processor but then I came to knew from various forums that the original Kernel does not benifit from HT because of the limitations of the Process Scheduler and that I have to apply patches from other people to make it working.
I downloaded the Andrew Morton's patch for this purpose but after succesful compilation when I booted the system it crashed at the very beginning and it provided two slightly different outputs at different boot attempts.

The first output was:

Can please somebody tell me what is the reason for this problem and how to remove it. Thankyou
